How to choose the suitable tungsten carbide product

To ensure that the selected tungsten carbide products meet your requirements, the following factors need to be considered:

1. Clearly Defined Application requirement

1)Application field

• Mechanical processing: If used for cutting tools, the hardness, toughness, and wear resistance of the processed material need to be considered. For example, when processing materials with high hardness such as mold steel, tungsten carbidecutting tools with high hardness and good wear resistance should be selected.
• 
• Mining: In terms of rock drilling tools, the hardness, abrasiveness, and harsh working environment of the rock should be considered. For the mining of hard rocks, high-strength and impact resistant tungsten carbides are required.
•  
• Mold manufacturing: For stamping molds, the appropriate tungsten carbideshould be selected based on the characteristics of the stamping material and the magnitude of the stamping force. If stamping thin steel plates, it may require tungsten carbides with good toughness to prevent mold cracking.

2)Working conditions

• Load situation: If subjected to high loads, high-strength tungsten carbides should be selected. For example, in heavy-duty gear machining, the cutting tool needs to withstand a large cutting force, and high-strength tungsten carbidecutting tools should be selected.
• Temperature environment: When working in high-temperature environments, such as hot forging molds, it is necessary to choose tungsten carbides with good high-temperature performance to ensure that their hardness and strength will not sharply decrease due to high temperatures.
• Corrosive environment: If in a corrosive environment, tungsten carbides with corrosion resistance or surface coating treatment can be considered to improve their corrosion resistance.

2. Understand the performance parameters of tungsten carbides

1)Hardness

• Hardness is an important indicator for measuring the ability of tungsten carbides to resist local deformation. Generally speaking, the higher the hardness, the better the wear resistance, but the toughness may decrease accordingly. You can balance the relationship between hardness and toughness according to specific usage requirements. For example, for precision machining tools, high hardness is required to achieve good cutting accuracy and surface quality; For rough machining tools, it may be necessary to reduce the hardness appropriately to improve toughness and prevent tool breakage.

2)Strength

• Strength includes flexural strength and compressive strength, reflecting the ability of tungsten carbides to resist fracture and deformation. When subjected to large loads or impacts, tungsten carbides with higher strength should be selected. For example, in mining, rock drilling bits need to have high bending strength and compressive strength to withstand the impact and compressive force of rocks.

3)Resilience

• Resilience refers to the ability of tungsten carbides to absorb energy without fracture when subjected to impact or vibration. For situations with harsh working conditions and impact loads, such as crushing equipment in mining machinery, it is necessary to choose tungsten carbides with good toughness to improve their service life.

4)Wear resistance

• The wear resistance determines the degree of wear of tungsten carbides during use. For applications that require long-term maintenance of dimensional accuracy and surface quality, such as precision molds and high-precision cutting tools, tungsten carbides with good wear resistance should be selected. The wear resistance of tungsten carbides can be evaluated by examining their chemical composition and microstructure. Generally speaking, tungsten carbides containing more hard phases (such as tungsten carbide) have better wear resistance.

3. Quality

• Check the appearance quality of tungsten carbide, including surface smoothness, absence of cracks, porosity and other defects. These defects may affect the performance and service life of tungsten carbide
• Understand the quality control system of the manufacturer, including the selection of raw materials, control of production processes, and testing methods for products. Choosing a manufacturer with a strict quality control system can ensure the stability of product quality.

     4.Cost

1)Price

• The price of tungsten carbideproducts varies depending on factors such as brand, performance, and specifications. When choosing, don't just pursue low prices, but consider the relationship between product performance, quality, and price comprehensively. Compare prices from different brands and suppliers, and choose products with high cost-effectiveness.

2)Service life

• Considering the service life of tungsten carbides, although products with higher prices may require larger initial investment, if their service life is long, it can reduce replacement frequency and maintenance costs, which may be more economical in the long run. For example, in mold manufacturing, using high-quality tungsten carbidemolds can produce more products and reduce the mold cost per unit product.

3)Maintenance cost

• Understand the maintenance requirements and costs of tungsten carbideSome products may require special maintenance and upkeep, such as regular coating repairs, sharpening, etc., which can increase the cost of use. When making a choice, consideration should be given to balancing maintenance costs with product performance and lifespan.

In short, choosing a tungsten carbide product that is suitable for one's own use requires comprehensive consideration of multiple aspects such as usage requirements, performance parameters, product quality, brand reputation, and cost factors. By delving into these factors and analyzing and comparing them with practical application situations, you can choose the most suitable tungsten carbide product for yourself, improving work efficiency and economic benefits.
